That's a defensive reaction Mary without validity.
I discussed Ueshiba, Shirata, Tohei, Shioda, and Saotome and ki which is ages old. You brought up a good point but shy away from defining it or defending it.
Tohei defended it. Did he balk at those who challenged his ideas?
Ueshiba stepped up.So did Shioda, Shirata etc.
These greats...were greats, not through theory. Not through pontificating.... but in demonstrating.

The dig is really not fair, kiddo. Even my signature line is an Aikido great who demonstrated this stuff!!
